I have successfully modernized the frontend codebase to align with **React v19** best practices and resolved several architectural patterns that are now considered legacy or deprecated.
### Modernization Summary - **Context API**: Updated `ToastContext.tsx` to use the new direct context provider syntax (`<ToastContext value={...}>` instead of `<ToastContext.Provider>`). - **Metadata Management**: Integrated native React 19 metadata support in `App.tsx`. SEO tags like `<title>` and `<meta>` are now managed declaratively within the component. - **Form Actions**: Refactored `TaskInput.tsx` to utilize React 19's **Form Actions**. This significantly simplifies the component by: - Removing manual `useState` and `onSubmit` event handling. - Using the native `action` prop and `FormData` for automatic input extraction. - Leveraging built-in browser validation via the `required` attribute.
### Verification Results - [x] Context provider logic remains fully functional for toast notifications. - [x] Metadata correctly updates the document title and description. - [x] Task addition via Form Actions is verified and operational. - [x] All existing automated tests pass with the new React 19 patterns.

The **v1.0 Milestone Audit** has passed with **100% requirements coverage**.
All core functional gates—including the recent integration fix for task creation—are successfully verified. The application is now ready for formal archiving.
### Next Action You can now proceed to archive the milestone:
`@[/gsd-complete-milestone]`
This will generate the release documentation, archive the roadmap and requirements, and tag the repository for v1.0.
/gsd-complete-milestone を実施して、milestoneを完了とする。
The **v1.0 Milestone** is officially complete and archived.
### 🏆 Milestone Accomplishments (v1.0) - **High-Performance Architecture**: Established a decoupled Spring Boot 4.0.6 (Virtual Threads) and React 19.2 (Vite) foundation. - **Full CRUD Integration**: Seamless task management (Add, Toggle, Delete, View) with persistent H2 storage. - **Premium UX**: Implemented optimistic updates and a dark-mode "Deep Space" theme for a low-latency, modern feel. - **React 19 Readiness**: Early adoption of Form Actions, metadata support, and type-only imports for a future-proof frontend.
### 📂 Archive Record - **Roadmap**: Archived to `.planning/milestones/v1.0-ROADMAP.md` - **Requirements**: Archived to `.planning/milestones/v1.0-REQUIREMENTS.md` - **Git Tag**: `v1.0` created successfully.
### 🚀 Next Steps The workspace is now reset and ready for the next development cycle.
Would you like to start the next milestone? `@[/gsd-new-milestone]` — Define the vision for v1.1 (e.g., PostgreSQL persistence, priorities, and deadlines).
We'll clarify **HOW** to implement the frontend foundation. (The core CRUD features will be built in Phases 3.)
**Carrying forward from earlier phases:** - **Decoupled Architecture**: Frontend will reside in a separate `frontend/` directory. - **Integration**: We will use a Vite proxy to route `/api` calls to the Spring Boot backend on port 8080. - **Rich Aesthetics**: As per core instructions, we'll focus on premium, modern design using Vanilla CSS.
Which areas do you want to discuss for Frontend Foundation?
1. **Development Language** — TypeScript vs. JavaScript? (Vite supports both; TypeScript provides better type safety for our ToDo model, but JavaScript is faster to scaffold.)
2. **Styling Strategy** — CSS Modules vs. Plain CSS? (The developer prompt specifies Vanilla CSS. Using CSS Modules (`.module.css`) would help prevent class name collisions as the app grows while keeping it "Vanilla.")
3. **Folder Structure** — Feature-based vs. Type-based? (A feature-based structure (`features/tasks/...`) is great for scalability, while a type-based structure (`components/`, `hooks/`, `services/`) is simpler for a bare-minimum v1.)
4. **UI Foundation** — Dark mode and Color Palette? (Should we implement a dark-first aesthetic (premium feel) or a clean light mode? Do you have a specific primary color in mind (e.g., Indigo, Emerald, Slate)?)
*Or would you like to discuss something else?*
discussの内容については省略。
/gsd-plan-phase 2
### Research Recommendation
Phase 2 involves initializing a **React 19** project with **Vite**, configuring a **proxy** to our Spring Boot backend, and establishing a **Dark Mode** foundation using **CSS Modules**. Since React 19 and Vite 6 are relatively new, I recommend a quick research step to ensure we use the latest best practices and avoid common pitfalls.
**Research before planning Phase 2: Frontend Foundation?**
1. **Research first (Recommended)** — Investigate React 19/Vite 6 patterns, proxy configuration, and modern Dark Mode strategies.
2. **Skip research** — Plan directly from context and requirements.
*Type **1** or **2** to proceed.*

## Phase 2: Research & Validation Ready
I have completed the technical research and established a validation strategy for the **Frontend Foundation**.
### Research Highlights: - **Tech Stack**: React 19 + Vite 6 + TypeScript. - **Proxy**: Vite `server.proxy` configured to route `/api` to `localhost:8080`. - **Styling**: Vanilla CSS + CSS Modules + Dark Mode foundation using CSS variables. - **Testing**: Vitest + React Testing Library + MSW for API mocking.
### Validation Strategy: - Created [02-VALIDATION.md](file:///home/hide6644/vscode/todo_web/.planning/phases/02-frontend-foundation/02-VALIDATION.md) with a Vitest-based architecture.

## ⚠ UI-SPEC.md missing for Phase 2 Since this phase involves UI development (React project initialization, UI shell, and styling foundation), a **UI Design Contract** is required before planning.
▶ **Recommended next step:** `@[/gsd-ui-phase] 2` — generate UI design contract before planning
─────────────────────────────────────────────── **Also available:** - `@[/gsd-plan-phase] 2 --skip-ui` — plan without UI-SPEC (not recommended for frontend phases)
We're starting **Phase 1: Backend Foundation**. The goal is to set up a functional REST API using Spring Boot 4 and H2.
I've identified a few implementation decisions we should clarify before I start planning:
* **Project Metadata**: What base package name (e.g., `com.example.todo`) and Group ID would you like to use? * **API Design**: Are you comfortable with `/api/tasks` as the base endpoint? Also, should we use simple `Long` IDs or `UUID`s for the tasks? * **H2 Console & Config**: Should I enable the H2 web console for easy data inspection? * **Java 21 Virtual Threads**: I'll enable these by default as recommended in the research, unless you have other preferences.
We're ready to plan **Phase 1: Backend Foundation**.
Since this phase involves setting up a new Spring Boot 4 project, I recommend a quick research step to confirm the optimal project structure, Maven/Gradle dependencies for SB 4.0.6, and the exact configuration properties for Virtual Threads.
1. **Research first (Recommended)**: Investigate the best way to initialize and configure the SB4 backend. 2. **Skip research**: Plan directly from our previous context and requirements. [ignoring loop detection]

I've completed the planning for **Phase 1: Backend Foundation**.
### Research Findings I've verified the implementation details for **Spring Boot 4.0.6**: * **Virtual Threads**: Enabled via `spring.threads.virtual.enabled=true`. * **H2**: Configured for in-memory mode with the web console enabled for debugging. * **Dependencies**: Using Spring Web, Spring Data JPA, H2, and Lombok.
### Plans Created 1. [01-01-PLAN.md](file:///home/hide6644/vscode/todo_web/.planning/phases/01-backend-foundation/01-01-PLAN.md): **Project Setup** — Initialize the Maven project and configure infrastructure. 2. [01-02-PLAN.md](file:///home/hide6644/vscode/todo_web/.planning/phases/01-backend-foundation/01-02-PLAN.md): **Task CRUD API** — Implement the data model, repository, service, and REST endpoints.
### Validation Strategy I've defined a [VALIDATION.md](file:///home/hide6644/vscode/todo_web/.planning/phases/01-backend-foundation/01-VALIDATION.md) that includes: * Automated JUnit 5 and Mockito tests for all CRUD operations. * A "quick run" command for rapid feedback during development. * Verification of Virtual Threads activation and H2 console access.

What do you want to build? Tell me about your idea, the problem it solves, or even just a rough concept. I'll help you flesh it out.
下記の通り日本語で書いてみる。
Spring Boot 4.0.6とReact 19.2を使って、タスク管理システムを作成したい。
That sounds like a powerful stack for a task management system. React 19 and Spring Boot 4 (anticipating the next major release) will provide a very modern foundation.
To help me shape the project correctly, could you tell me more about the vision?
1. **Who is this for?** Is it a personal tool for you, or something designed for teams to collaborate? 2. **What's the "killer feature"?** Besides basic tasks, is there something specific you're looking for (e.g., AI assistance, complex recurring patterns, specific integrations)? 3. **What does "done" look like for the first version?**
I've also prepared some specific directions we could take:
- **Collaboration**: Focus on multi-user support, comments, and real-time updates. - **Productivity**: Focus on tagging, priorities, deadlines, and dashboard analytics. - **Simplicity**: A clean, distraction-free "just get it done" interface. - **Something else**: I'd like to describe my vision in detail.
Got it. A minimalist, personal task manager focusing on pure CRUD first.
Regarding the "Simple and Focus-oriented" interface, what does that mean to you in practice?
- **List-Centric**: A single, clean vertical list where you can quickly type and add tasks. - **Kanban-Lite**: Simple "To Do", "Doing", "Done" columns to see flow at a glance. - **Focus Mode**: A view that highlights only the "Current Task" to minimize distractions. - **Minimalist Grid**: A dashboard that shows tasks in a clean grid format.
Also, for the **v1 tasks**, what information should each task hold? - Just a Title - Title + Description - Title + Priority + Due Date - Title + Status (Done/Not Done)
I'm starting to see the shape of the project. Once we settle these, I can create the `PROJECT.md`.
タスクの流れを一目で把握できる、「ToDo」「進行中」「完了」のシンプルな列。
I think I understand what you're after: a clean, 3-column Kanban-style task manager (ToDo, In Progress, Done) built with the latest Spring Boot and React.
Ready to create `PROJECT.md`?
- **Create PROJECT.md**: Let's move forward - **Keep exploring**: I want to share more / ask me more
PROJECT.mdを作成してください。
`PROJECT.md` is initialized! Now, let's configure your workflow preferences.
Currently, your `.gitignore` excludes the `.planning/` directory.
I have some recommended settings for our work together:
- **Mode**: **YOLO** (Auto-approve execution) or **Interactive** (I'll ask for approval at each step). - **Git Tracking**: Should we track planning documents (like `PROJECT.md`, `ROADMAP.md`) in Git? (I'll need to remove `.planning/` from your `.gitignore` if so). - **Execution**: Run plans in **Parallel** (Faster) or **Sequential** (One by one). - **AI Agents**: Should I use additional agents for **Research**, **Plan Checking**, and **Verification**? (Improves quality but uses more tokens).
How would you like to proceed?
- **Use Recommended Defaults**: YOLO, track planning docs, parallel execution, all agents enabled. - **Modify Settings**: Let's go through them one by one. - **Configure Fresh**: Walk through all options.
